Hello! I want to make an inquiry I bought a 90 liter escorial electric water heater. 1 month and a half ago, my husband installed it, which is not registered, but he knows a lot about what is pipe and electrician, we were bathing for a month and a half since we did not grab the coldest days of winter and we bathed with the hot water heated barbaro and from one day to the next the lamp turned off and I do not heat any more, we call the guarantee but they ask me for information from a registered electrician. I have no problem paying someone to pass me the data of one but I do not want to lose a new hot water tank thank you very much I would appreciate an answer !!!
